METAL FORGI NG AND SHAPING PRESS.

SPECIFICATION forming part of Letters Patent NO. 505,955, dated October3, 1893.

Application filed June 27. 1892. Serial No. 488.166. (No model.)

To all whom it may concern:

Be it known that we, BENJAMIN F. PE

COOK, residing at Anniston, in the county of Calhoun and State ofAlabama, and FRANCIS TOY PEACOOK, residing at Sparrows Point, in thecounty of Baltimore and State of Maryland, citizens of the UnitedStates, have invented certain new and useful Improvements in MetalForging and Shaping Presses; and

' we do declare the following to be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

Our invention relates to metal forging and shaping presses.

The object of our invention is to forge axles,

rods, shafts and the like, by means of a fluidpressure press of novelconstruction, whereby the output of the machine is accomplished in asimple, efficient, and economical method.

Figure 1 is a horizontal sectional view and partial plan of a machineembodyingour invention. Fig. 2 is a side elevation of the same,partially in vertical section. Fig. 3 represents an end elevationof themachine. Fig. 4: represents a side elevation of a modified form of amachine, to which we have also applied our improvements.

I Our invention consists in the following construction and combinationof the opera tive parts, which will first be fully described and setforth in the specification, and the features of novelty therein thenpointed out and claimed.

In' the drawings -A represents the foundation bed upon which our machineis mounted.

. and the standards themselves are mutually braced against outwardlythrust strains or blows, tending-to-force the standards fartherapart,'by the'combined brace and guide rods Io. The'standa'rd's'B carrythe die-holders D "Inthe duplex machine two cross-heads F v are employedwhich reciprocate-back and forth upon the stay and guide rods 0. Thesecross-heads carry the movable die-holders G and the movable dies H, thelatter being arranged to reciprocate adjacent to and in line with thestationary dies E.

For the purpose of reciprocating the movable dies H simultaneously thefollowing mechanism is preferably employed: I is a fluid-pressurecylinder disposed below the machine and interm'ediately of the standardsB. J is the cylinder-piston having a vertical movement therein which isadapted to operate a toggle device K, for the purpose of operating themovable dies. This toggle K consists of a vertically moving piece Lhaving suitable connection with the piston J. To this piece arepivotally connected four levertoggle arms M, which in turn are pivotallyconnected, respectively, to the oppositely arranged cross-heads F.

In making connection between the crossheads F and the toggle-armsM, soas to secure a jointed pivotal action we preferably project intocorrespondingbearings on' the inner sides of the toggle-arms M, and holdthe latter in position. These pieces N we pro,- (gfer to bolt to thecross-heads F in any suitable manner. The outer ends of the togglearms Mare rounded, being received into corresponding depressions or bearingsin the opposite faces of the cross heads F, and abutments-P are formedat the outer ends of these bearings in the cross-heads which serve tohold the toggle-arms M in position and upon the pintles 0. An upwardmovement of the piston J operates upon the toggle de-i vice K to movethe dies H toward the dies E.

For the purpose of returning the piston J, or in other words moving thedies H away from the dies E, we provide a second fluidpressure cylinderQ, having a piston R which rests upon the top of the vertical piece L ofthe toggle K. This piston or ram R will, when pressure is introducedinto the cylinder Q, force the toggle down and the dies-apart.

We prefer to provide the cylinder Q with oppositely extending arms Swhich terminate in bearings T secured to and carried 'by the upper stayand guide rods 0, the fluid pasth-rough theconnecting bolts V.

sages to the cylinder .Q being through-.the bearings Tand the arms S."The'onter ends of the arms S are journaled in the bearings T so as tooscillate therein, thereby permit- 5 ting a limited rocking movement tothe cylinder Q to compensate for any lateral movement of theverticirllymeiring piece Ifiof the toggle K. In like manner the bearings'flof the cylinder Q may be moved bodily along the rods 0 to provide forany-undue endwise movement of the toggle.

It will be understood by the term fluidpressure cylinders. thatanymlrnownnfluid or, gaseous agent may be employeds'ubh as waz 5 ter,oil, steam, air, gas,-'caloric *o1 theflike.

In like manner wemay vary the form of our togglegear and of the fluid-pressure cylinders.All these changes and modifications we can make and still comewithin thescope'of our invention.

We prefer to leave the opposite ends of the diesE H open sothat-aportion of the forgings therein may project axially at the oppositeends, whereby the operator may secure said-ends in slingswor tongs froma movable crane, and thereby secure perfect control in I" manipulatingthe forging in the various blows -or strains to which he maysubject it. .We cla im--- I 1.4 Ima forgiirg machine empress; thecombinationuofwdie holding istandards; stayr'and guide rods connect-ingt thetsame a cross-head V carry-i ngra idieanovin g onmsaidr rodst-aitoggle- Hdeviceaanranged between their cross-head and I thestandardsfomactuatingisaid reross head,
